F(x)=-9x- 2 find f(7)

x= -1/5

Step-by-step explanation:

1

Add 9x9x to both sides.

x+9x=-2x+9x=−2

2

Simplify  x+9xx+9x  to  10x10x.

10x=-210x=−2

3

Divide both sides by 1010.

x=-\frac{2}{10}x=−102

4

Simplify  \frac{2}{10}102  to  \frac{1}{5}51.

x=-\frac{1}{5}x=−51

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
